Question

尝试显示我的类对象的rdlc报告

这是班级

public class BillInfo
{
    public String Name { get; set; }
    public String Date { get; set; }
    public String splInstructions { get; set; }
    public List<OrderItem> oItems { get; set; }
    public String GrossTotal { get; set; }
    public String DiscountAmount { get; set; }
    public String NetTotal { get; set; }
}

public class OrderItem
{
    public OrderItem() { }
    public OrderItem(String sNo, String Qty, String Amt, String ttl) 
    {
        this.SNo = sNo;
        this.Quantity = Qty;
        this.Amount = Amt;
        this.Total = ttl;
    }

    public String SNo { get; set; }
    public String Quantity { get; set; }
    public String Amount { get; set; }
    public String Total { get; set; }
}

现在我在数据源窗口中添加类 BillInfo 的数据源对象并添加了一个报表查看器，现在当我尝试添加数据源vaue作为bill信息类的对象时，它给了我这个奇怪的错误

this.BillDataViewer.LocalReport.ReportPath = "C:/Users/Guest1/Desktop/Billinator/Billinator/MainReport.rdlc";
this.BillDataViewer.LocalReport.DataSources.Add(new ReportDataSource("BillInfo", MainForm.GetBillData()));
this.BillDataViewer.RefreshReport();

我添加数据源的第二行给了我这个错误

Value does not fall within the expected range.

“at Microsoft.Reporting.WinForms.ReportDataSource.set_Value（Object value）\ r \ n在Billinator.ReportViewer.ReportViewer_Load（Object sender，EventArgs e）中的C：\ Users \ Guest1 \ Desktop \ Billinator \ Billinator \ ReportViewer .cs：在System.Windows上的System.Windows.Forms.Form.OnLoad（EventArgs e）\ r \ n，在System.Windows的System.Windows.Forms.Control.CreateControl（Boolean fIgnoreVisible）\ r \ n中的第23行\ r \ n。在System.Windows.Forms.Control.WndProc（Message＆amp; m）\ r \ n的System.Windows.Forms.Control.WmShowWindow（Message＆amp; m）\ r \ n中的Forms.Control.CreateControl（）\ r \ n系统.Windows.Forms.Control.ControlNativeWindow.WndProc（消息＆amp; m）\ r \ n在System.Windows.Forms.NativeWindow.DebuggableCallback（IntPtr hWnd，Int32 msg，IntPtr wparam，IntPtr lparam）“

请建议我哪里出错

使用Object作为DataSource的RDLC
